"The lighting needs to be as flexible as possible". Control natural light with shades, horizontal or vertical blinds, and dimmers, designers suggested.
These ranged from 101 to 115 KYA [21] (Fig. 3, shaded horizontal bar).
Alternatives for shading devices, e.g., horizontal panel, horizontal multiple blades, vertical fin, slanted vertical fin, and egg crate (Fig. 2b), are provided in the system.
The main objective of this paper is to introduce a simple quick tool for architects represented by a design chart that determines the dimensions of an external horizontal shading device over an equator-facing window as a function of the latitude and the shading height, resulting in an automatic seasonal adjustment.
Summarized correlation models of the shading performance of horizontal shading devices can be useful under general condition for buildings.
This study provides a methodical procedure to establish summarized correlation for evaluating shading performance of horizontal shading devices based on the shading ratio and shading coefficient via the simulation of shading variables of 22 25° latitude north in Taiwan.
Results show generally high satisfaction with daylit work environment and positive effect of the horizontal shading strategy.
Ultimately, it is found that the combination of both natural ventilation and horizontal shading devices improves thermal comfort for occupants and significantly reduces cooling energy demand.
The results show significant improvement of energy performance by choosing a shading system with horizontal elements using the optimum inclination angle for the shading device and the minimum inclination for the photovoltaic panels.
The paper aims at evaluating the energy performance of an office building that integrates photovoltaic panels in a mobile shading system with horizontal elements, based on simulations, while also defining the optimum performance parameters: shading degree, orientation and inclination angle.
